Rating: The evidence grade blends site density/proximity, crowdsourced signal when present, and carrier-filed coverage. Missing sources are excluded rather than treated as zero.

About AT&T Coverage Near Sparrows Point, MD 21219
Evidence suggests usable AT&T coverage in Sparrows Point, MD 21219. Our analysis combines FCC cellular license records, crowdsourced OpenCellID observations when available, and carrier-filed FCC BDC coverage. Within 5 miles of Sparrows Point, MD 21219, those sources resolve to 26 grouped AT&T sites; the nearest is approximately 0.21 mi away.
Where a crowdsourced reading is unavailable, signal is estimated with Free-Space Path Loss (FSPL) and FCC-registered or band-typical effective radiated power (ERP). The best available site value is -37.2 dBm. It is a planning estimate, not a promise of device-level or indoor performance.
We found 25 sites with mid-band spectrum. Carrier filings and device observations provide additional context, but band presence alone does not confirm active 5G.
